The DC182 series of contactors has been designed for direct current loads, particularly motors as used on electric vehicles such as industrial trucks, airport tractors, and such like.
They have double breaking main contacts with silver alloy contact tips, which are weld resistant, hard wearing and have excellent conductivity.
The DC182 main contact circuit, designed for motor reversing, is such that it has a built in failsafe, so that if both coils are energised simultaneously the contact arrangement is open circuits.
The DC182 is a monoblock construction, resulting in a neat compact design which is compatible with modern electronic control systems. Main terminals can be configured in a variety of ways in order to suit the application.
Installation: Supplied with a mounting bracket as standard, or alternatively supplied with M5 tapped holes.
Magnetic Blowouts: Fitting of magnetic blowouts make the polarity sensitive and the positive markings on the top cover of the contactor must be observed. Suffix 'B' denotes the fitting of magnetic blowouts.
Auxiliary Contact: Denoted by 'A', a double circuit normally open, normally closed microswitch auxiliary contact can be fitted, ratings as shown below.
